10 Claims.

This invention relates to atomizers for perfume, toilet water, or thelike, and particularly to such an atomizer of small and compact form forcarrying in a pocket or purse.

The primary object of the invention is the provision of an atomizer ofthis character of improved construction, whereby to enhance thepracticability and commercial value and to increase the operatingefficiency thereof.

A further object of the invention is the provision of an atomizer ofthis character of unique construction and arrangement of parts, wherebythe pump and liquid container are axially aligned and entirely separatedand out of communication orie with another.

Other objects and advantages of the invention will be apparent from thefollowing detailed description and from the accompanying drawingillustrating one embodiment thereof, in which- Figure 1 is an enlarged.central longitudinal section of an atomizer embodying the invention,with the parts in closed position and with parts in full; Fig. 2 is asimilar view reduced in size from that of Fig. l, but enlarged withrespect to commercial size, with the parts in completely separatedposition; Fig. 3 is a side elevation of Fig. 2 turned a quarter wayaround;

Fig. 4 is a similar side elevation in the same position as Fig. 2, andFigs. 5 and 6 are sections on the lines 5-5 and 6-6 Ataken respectivelyon Figs. 1 and 2, with the former reduced in s1ze.

By reference to the drawing, it will be noted that the device embodyingthe invention includes a compressor cylinder I and a receptacle 2, for

the liquid to be sprayed, disposed in axial alignment and one telescopedwith the other to permit relative axial reciprocatorry movementsthereof. In the present instance, the inner end of the wall of thecylinder I has an extension or tiiirt'portion 3 which telescopes overthe side The receptacle 2 has its inner end closed to form a bottom 6,while its outer end is open preferably terminating in an outwardlydirected radial edge ilange l.

A bushing 9` is flxedly secured in the outer end portion of thereceptacle wall 4, being sealed therein in any suitable manner, and hasits outer end ilanged to engage over the arged edge 1 of said wall. Aplug I0 is removably threaded into the bushing 9 and has suitable gasketseating engagement therewith to prevent leakage.

A protecting sleeve II is provided on the receptacle 2 around its Wall 4in spaced relation 55 thereto, so as to receive the extension or skirtend 3 of the cylinder I\ therebetween. This sleeve is attached to thereceptacle by inwardly flanging its outer end and depressing such flangeto provide a countersunk inwardly projecting edge ilange in coactionwith the edge flange 1 of the receptacle wall and between it and theoutwardly flanged edge of the bushing 9, which latter seats within thedepressed portionof the sleeve end and serves both to center the sleeverelative to the receptacle and to hold the inturned sleeve end inengagement with the receptacle wall. in fixed engagement .with such wallbut is free to turn relative thereto for the purpose hereinafterdescribed.

A discharge nozzle I2 is mounted in the bottom or inner closed end `ofthe receptacle 2 adjacent to the outer edge of the bottom and has itsbore in communication with the interior of the receptacle preferablythrough a porous packing material I3 of felt, or other suitablematerial, in the bottom of the receptacle. This nozzle is of shallowform and projects only a short distance from the end of the receptacle.The receptacle is also provided with a vent tube I4 which preferablyopens into the receptacle near its outer end, While its other end isprojected through an opening in the bottom of the receptacle near oneedge thereof and preferably in a position substantially diametricallyopposed to the nozzle I2. The outer end of the vent tube opens to theatmosphere and such end is substantially in the same cross plane of thedevice as the discharge end of the nozzle I2.

A stem I8 is fixed to the inner or bottom end of the receptacle 2intermediate the nozzle I2 and vent tube I4 and projects axiallytherefrom into theA compressor cylinder I. In the present instancel thisstem is attached to the receptacle by providing the inner end of thestem with an axially projecting lug I9 which is inse'ted into acentrally disposed inwardly flanged opening in the bottom of thereceptacle and flrmlysecured therein by cementing, soldering, or anyother suitable manner. The stem I8 projects through a web 20 in theinner end of the body portion of the cylinder' |suoh web cooperatingwith the outer closed end of the cylinder i to form a compressor chamber2I. Within this chamber the ,stem I8 is provided with a compressorplunger 22 of anysuitable construction. The outer end of the chamber 2|is closed by a plug 23 which, in the present instance, is threaded inthe cylinder and is pref- The sleeve, however, is not held erably sealedtherein by cementing. An expansion spring 24 of the conical type isdisposed in the chamber 2| with one end thrust against the plug 23 andits 'other end thrust against the piston 22.

The stem |8 has a longitudinally extending bore 25 therein extending tonear the inner end of the stem with its outer end in communication withthe interior of the compressor chamber 2| through a small passage 26 ina plug 21. which is secured in the outer end of the stern bore andserves, in the present instance, to attach the piston 22 to the stem.The instroke of the piston within the compressor chamber is limited bythe outer end of the plug 21 striking an inwardly projected centralportion of the plug 23.

A discharge orice 30 for air compressed within the chamber 2| isprovided in the stem wall from the inner end portion of the stem bore 25in position to direct its discharge across the outer end of thedischarge nozzle |2 in impinging relation thereto, so as to draw liquidfrom the receptacle 2 through the nozzle and porous packing I3 andeffect its discharge in spray-form from the nozzle transversely thereofand outwardly with respect to the stem. 'This spray discharge from' thenozzle is directed outwardly from the device through an elongated slotor opening 3| provided in the extension or skirt portion 3 of thecylinder wall .The opening 3| extends .from the inner open end of theWall portion 3 to near the web 20 and is of suicient length for -thenozzle I2 to be exposed to the outside during substantially the' fulloperating stroke ofthe compressor. `When the cylinder and receptacle 2are in completely telescoped or compressed relation, the outlet ends ofthe nozzle |2 and vent tubev Mabearagainst and are closed by a gasket 33which' seats against the receptacle side of the web 20. It is thusapparent that when the two parts of the atomizer are in closed relationthe two outlets from the receptacle 2 are sealed to prevent any leakagetherefrom.

The stem 3 is preferably provided with a feather or rib 34 at one sidethereof Working in a recess in the web to prevent relative turning ofthe' cylinder and receptacle 2. When the atomizer parts are in closedrelation, substantially as shown in Fig. 1, the sleeve completely coversand closes the opening 3| in the skirt portion of the cylinder Thissleeve also has cooperative action with such skirt portion to limittheinward Working strokes of the parts. so as to prevent a completeclosing of the opening 3| during a spraying operation of the device, andalso to effect a locking of the parts in completely closed relation. Forthis purpose, the skirt portion 3 is provided at opposite sides thereofwith longitudinally extending :grooves or recesses 36 receiving guidepins 31 in the a-djacent end portion of the sleeve Such recesses havestraight portions suiiiciently long to take care of the full operatingstroke of the parts, such stroke being stopped at its inner end byengagement of the pins 31 with aligned shoulders 38 in the inner endportions of the recesses 36. The inner ends of the recesses 36 adjacentthe shoulders 38 are oiset and then continue inward and laterally inbayonet slot form, as shown at 39, so that the pins may be turned intothe laterally angled ends of such portions to lock the atomizer parts inclosed relation with the gasket 33 in sealing engagement with theprojecting ends of the nozzle I2 and vent tube I4.

In an operation of the device, presuming the parts to be in closedlocked relation, the sleeve is rst turned to release its pins 31 fromthe laterally extending end portions of the recessed parts 39, therebypermitting the sleeve and detached receptacle 2 to be moved outwardrelative to the cylinder to the full limit of the outward stroke, by theaction of the spring 24, which movement carries the piston 32 to theinner end of the cylinder. The operator may now effect successive inwardmovements or strokes of the parts ofA the device by applying successivepressure on the ends of the device between the thumb and a linger of ahand by which it is held. This action compresses air Within thecompressor chamber 2| and such air forcefully discharges from thecompressor through the orice 30 in a small stream which is directedacross the liquid discharge nozzle |2, thereby effecting a drawing ofliquid from the receptacle and a discharge of the same in spray-formlaterally from the device through the opening 3|.

It is apparent that I have provided a very compact and eilicientatomizer of the character described, in which the compressor unit andliquid container are disposed at opposite ends, with the plunger of thecompressor unit xedly projecting from the inner end of the container andalso with the discharge from the container arranged between the adjacentends of the compressor unit and container and adapted to have itsdischarge transversely thereof. It is also apparent that both the liquiddischarge nozzle and the air vent are `disposed in enclosed protectedrelation Within the device and are completely sealed to prevent leakagewhen the compressor cylinder and container ar'e in cl'osed or compressedrelation, and'also that there is no communication at any time` betweenthe interior of the compressor cylinder and that of the liquidcontainer.

I wish it understood that my invention is not limited to any specicconstruction, arrangement or form o'f the parts, as it is capable oinumerous vmodifications and changes Without departing from the spirit ofthe claims.
